NBC News White House correspondent Kristen Welker has the task of keeping the second and final presidential debate under control when President Trump and former Vice President Joe Biden meet Thursday at Belmont University in Nashville.

The Commission on Presidential Debates is giving Welker a hand in avoiding the constant interruptions that plagued the first showdown on Sept. 29. The microphone of the candidate not speaking will be muted during the opening two minutes for each of the six segments of the 90-minute debate, which will air across the major broadcast and cable news networks.

Welker, 44, is well acquainted with both candidates, having covered Biden’s years in the Obama administration and Trump’s first term in the White House. She joined NBC News in 2010 after a five-year stint as a reporter and anchor at TV station WCAU in her hometown of Philadelphia.
